SPECIFICATION forming part of Letters Patent No. 301,316, dated July 1,1884.

Application filed March 20, 1.884. (No mmlell) T0 osZZ whom, it wartyconcern Be it known that we, Louis ZINKAND and ADAM Honnnnnnnrrr,citizens of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented a certain new and usefulImprovement in Dumping-\Vagons; and we do hereby declare that thefollowing is afull, clear, and exact description of the invention, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of thisspecification.

Our invention relates to an improved dumping device for wagons; and itconsists of a bed hinged to the rear ends of side rails which connectthe rear axle to the bolster, a curved rack attached to both sides ofthe bed, and a pinion to engage the same supported on a shaft havingbearings secured to said side rails. A crank is attached to the shaft togive the requisite movement, and a flanged roller is used as a stay tothe curved rack.

The mechanism is illustrated in the accompanying drawings, in whichFigure I is a side view of the dumpingwagon. Fig. II is a fragmentaryplan of the dumping device.

Similar letters refer to similar parts throughout the several views.

The runninggear of the wagon is like those in general use, the noveltyconsisting in the curved rack and pinion and minor parts, as will behereinafter fully set forth. The side rails, L, connect the rear axle tothe bolster, the rear ends of which are attached to the bed by hinges B,slightly to the rear of the hind axle. To the sides of .the bed A isbolted the curved rack The curve of the rack has for its center thecenter of the hinge- 0 grooved roller D embraces the back of the.

rack and serves as a stay and guide.

The operation is thus: To discharge a load of sand or other material,turn the crank so as to elevate the front of the bed until gravitycauses the discharge, then the bed is lowered again to the rails. Therack may be pivoted to the bed, and may then have a different curve fromthat heretofore described, and then the relation of the curved rack tothe pinion would be dependent wholly on the grooved roller. 7

Having fully described our invention, what we desire to secure byLetters Patent is In a dumping-wagon, the bed A, hinged to the rear endsof side rails, in combination with shaft I, with crank to operate thesame, pinions O, curved racks E, with arresting-hook on end of same, andgrooved roller D, substantially as set forth.

In testimony that we claim the foregoing as our own we aiiiX oursignatures in presence of two witnesses.
